Abstract

We analyze symmetric pure strategy equilibria in dynamic sponsored search auction games using simulations by restricting the strategies to several in a class introduced by Cary et al. [1]. We show that a particular convergent strategy also exhibits high stability to deviations. On the other hand, a strategy which yields high payoffs to all players is not sustainable in equilibrium play. Additionally, we analyze a repeated game in which each stage is a static complete-information sponsored search game. In this setting, we demonstrate a collusion strategy which yields high payoffs to all players and empirically show it to be sustainable over a range of settings.

赞助搜索拍卖中动态竞价的均衡分析

在Cary等人[1]引入的一个类中，我们通过将策略限制为几个，使用模拟分析了动态赞助搜索拍卖博弈中的对称纯策略均衡。我们证明了一个特定的收敛策略对偏差也表现出很高的稳定性。另一方面，对所有参与者都产生高收益的策略在均衡博弈中是不可持续的。此外，我们分析了一个重复博弈，其中每个阶段都是静态的完全信息赞助搜索博弈。在这种情况下，我们展示了一种共谋策略，它可以为所有参与者带来高回报，并通过经验证明它在一系列设置中是可持续的。
